Application filed March 16, 1-912. Serial No. 684,274.

To all whom it may concern:

Be it known that I, SAMUEL G. PERRY, a citizen of the United States, residing at London, in the county of Laurel and State of Kentucky, have invented a new and useful Railway-Switch; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a new and useful railway switch.

It is the primary object of this invention to improve the structure of the switch mechanism shown in the drawings and set forth in the application, filed Oct. 18, 1911, Serial No. 655,1-14, and to provide an improved switch throwing mechanism adapted to be operated by a member ona moving car.

Another object of the invention is the pro vision of a switch, which when accidentally or otherwise left open, will automatically close upon the approach of a moving train.

A further object of the invention is to provide a lock for the switch adapted to be actuated by a member on a moving car or train, so as to release or unlock the switch, before the switch is thrown. This switch is provided with the usual signal, which indicates whether the switch is open or closed. If the switch is accidentally or otherwise left open, and the moving train is approaching the switch from the front on the main line, the switch mechanism is first unlocked automatically by the member on the moving train, after which the switch is automatically closed by the same member on the train. This operation is carried out in cases when the train is to continue straight ahead. However, if the train is approaching the switch on the main rails in the rear of the switch points, the switch is first automatically unlocked by the same member, after which the switch points are thrown automatically by the flanges of the car wheels.

The invention comprises further features and combination of parts, as hereinafter set forth, shown in the drawings and claimed.

In the drawings :'Figure 1 is a plan view of the improved railway switch embodying the features of the invention. 2 is a similar view, showing the switch points thrown in difierent positions.

15. Fig. 17 is a view in perspective of an oscillatory forked member having two flanged wheels, one of which 18 to be thrown in engagement with the rails, for actuating the mechanism in Fig. 15, while the other is brought in play to operate the devices shown in Figs. 11, 12, 13, and 14.

Referring to the drawings 1 and 2 desig nate the rails of the main line, on one side of .the switch points, while 3 and 4: denote the main rails on the other side of the switch points, whereas 5 .and 6 designate the rails of the siding or branch line. The switch points? and 8 are pivoted at 9 and 10. Con necting the free ends of the switch points by the straps 12 is a "bar 13, in which a slot 1 1 is formed. Pivoted in the slot 1 1 is a latch member 15, between which and an angular lug 16 of the bar 13, a spring 17 is interposed, the action of which normally holds the latch member 15 pressed upwardly, so that the lug 18 of the latch member will engage on either side of the locking bolt '19, which is mounted in guides '20 on the ties 21.

The locking bolt 19 is provided with diagonally opposite recesses 22 nd 22 having beveled portions 23, so that when the lug 18 is in registration with either one of the re cesses, the bar 13 may be reciprocated transversely of the rails, thus throwing the switch points to an open or closed position. Pivoted at 25 is an angular lever 26, one arm of which has one end of a rod 27 connected to it, while the other end of the rod 27 is pivoted at 28 to the three armed rocking member 29, which is pivoted at 30. This three armed rocking member has a slot and pin connection 31 with the bar 13, so that when the member 29 is rocked, the bar 13 will be thrown one way or the other, to in turn throw the switch points. Adapted to reciprocate transversely of the rails, one upon each side of the switch points are the bars 33 and 34. The bar 33 is provided with a slot and pin connection 35 with the other arm of the angle lever 26. The bar 34 is also provided with a slot and pin connection 36 to one arm of the angle lever 37, which is pivoted at 38. The other arm of the lever the other end of which rod 39 is pivoted at 40 to the three armed rocking member 29. Pivoted at 41 is a lever 42, to one end of which a rod 43 is connected. lVhen this rod 43 is reciprocated in the direction of the switch point, the lever 42 is oscillated. The lever 42 is provided with a slot and pin connection 44 with the locking bolt 19, so that when the lever 42 is manipulated the bolt 19 will in turn be reciprocated;

The bolt 19 has secured to it by the pins 19 and 19, a spring 19 which arches upwardly substantially at its central portion, between the guides 20, in order to hold the bolt 19 in one position or the other. pins 19 and 19 not only secure the spring 19 in position, but also constitute means for limiting the bolt 19 in its movement.

Pivoted to the rails 1, 2, 5 and 6 as at 46 are the depressible bars 47, 48, 49, and 50. The pivots 46 of these depressible bars are in the form of slot and pin connections, as shown at 51 in Figs. 11 and 12. Mounted in bearings 52, and in the bearings of the said rails 1, 2, 5 and 6 are the rocking rods 53, 54, 55, and 56, which are provided with cranks 57, 58, 59, and 60. These rocking rods are also provided with the cranks 61, 62, 63 and 64. The'depressible bars 47, 48, 49 and 50, which are spring tensioned as shown at 66 in Figs. 11 and 12, cooperate with the cranks 61, 62, 63 and 64, so as to rock the said rocking rods. The end 68 of the rod 43 connects to the crank 59 of the rocking rod 55.

Pivoted at 69, 70, 71 and 72 are the switch actuating bars 73, 74, 7 5, and 76, which are held adjacent the rails by the springs 77, the tension of which is regulated by the nuts 78. Each of the switch actuating bars is The the direction of the arrow 0.

If the switch is accidentally orotherwise.

left open, as shown in Fig. 2, and a train is approaching the switch points 111 the direc- =tion of the arrow at, the wheel 81, which is normally in engagement with the rail 2 in this case actuates the switch unlocking bar 82, which is pivoted at 83, by the flange 84 of the wheel coming in contact therewith.

This operation is performed when the train is to continue straight ahead on the main line. It will be observed that this switch unlocking bar 82 is positioned, so that the flanges of the car wheel will not contact therewith ordinarily. The free end of this bar 82 is guided in the guide 85. When the bar 82 is actuated, it in turn actuates the bell crank lever 86, by virtue of its connection 87. The bar 82 is pivoted upon a guide ,rail 83, as shown clearly in Figs. 15 and 16. 37 has one end of a rod 39 connected to it, 1

The bell crank lever 86 has its arm 89 conactuate the bolt 19, so that the bar 13 may be reciprocated, in order to restore the switch points 7 and 3 to the positions shown in Fig. 1, whereby a train may continue straight ahead upon the main line. After the bar 13 has been unlocked in this manner,

the flange 84 of the wheel 81 actuates the supplemental switch actuating bar 95, which pivoted at 96 upon a guide rail 97. The

free end of the bar 95 is guided in the guides 98, The bar 95 is pivoted, by virtue of the lug 99 to the transversely reciprocating bar .33, as shown at 100. hen the bar 95 is thrown away from the rail 2 by the flange '34 of the wheel 81, the reciprocating bar 33 is actuated in the direction of the arrow Z), and by reason of the slot and pin connection with the lever 26, the three armed member 29 is oscillated, which in turn will actuate the bar 13, thus restoring the switch point to the positions shown in Fig. 1.

However, it a train is approaching the switch points on the main line in the direc- 'tion of the arrow 0, while the points are in the positions shown in Fig. 2, the switch unlocking bar 102 is actuated by the flange 84 of the wheel 81, as shown clearly in F igsQ 7 and S. This bar 102 is pivoted at 103, and

is arched upwardlyv between its ends, as

shown in Fig. 7, with its free end guided in the guides 104. When the bar 102 is actuated, the bell crank lever 105 which is pivoted at 106 is actuated, by virtue of the rod connection 107. This rod 107 pushes against the bell crank lever 105 and oscillates it in The arm 106 of the lever 105 is connected at 109 to the rod 43, and when the bell crank lever 105 is oscillated in the direction of the arrow 6, the rod i3 is moved, which in turn will swing the lever 12 upon its pivot i1, thus throwing the bolt 19, in order that the switch points 7 and 8 may be thrown by the flanges of the car wheels. As the train leaves the switch, still traveling in the direction of the arrow 0, the switch is again locked, by virtue of the wheel 110 of the forked member 111 (which also carries the wheel 81) coming in contact with the depressible bar 48. When the bar 48 is depressed, the rocking rod 54: is actuated, because of the crank 62 being actuated. If desired the wheel 110 need not be thrown in a position to actuate the depressible bar 18.

Referring to Fig. 1, it will be seen that when a train is moving in the direction of the arrow (Z, the flange of the wheel 110 depresses the bar 47, which in turn actuates the rocking rod 53, by virtue of the crank 61. As the rod 53 is rocked, the crank 57 contacts with the shoulder 113 on the rod 90, moving the rod 90 in the direction of the switch points, thus oscillating the lever 42, which in turn throws the bolt 19, thus releasing or unlocking the bar 13. This operation is performed when the train is to pass on the branch line. After the bolt 19 is thrown in this manner, the flange of the wheel 110 throws the switch actuating bar 74, against the action of its spring, thereby moving the bar 33 transversely of the rail. \Vhen the bar 33 is thus actuated, the three armed member 29 is oscillated on its pivot, which in turn throws the bar 13 and the switch points 7 and S with it to the positions shown in Fig. 2, thus permitting the train to take the branch line. As the train leaves the switch mechanism, the flange of the wheel 110 actuates the depressible bar 50, which in turn rocks the rod 56, by virtue of the crank 64. When the rod 56 is actuated the crank 60 contacts with the shoulder 116 of the rod 43, thus unlocking the switch points. As the train continues on the branch line, the flange of the wheel 110 actuates the bar 7 5, which in turn moves the bar 3 1. \Vhen the bar 34L is transversely moved, the bell crank lever 37 is oscillated, which in turn will throw the switch points, by means of the rod 39, the three armed member 29, and the bar 13.

\Vhen a train is approaching the switch on the branch line in the direction of the arrow 7L, the switch is unlocked by depressing the bar 49, so as to rock the rod 55, which in turn will push the rod 43 in the direction of the switch points 7 and 8. After the switch has been unlocked as the train is moving in this direction, the switch points are thrown by actuating the bar 7 6.

As the train leaves the switch passing in I thesame direction of the arrow 71,, the switch is again unlocked and thrown or restored to its former position by first actuating the depressible bar 48, and then the bar 73. To move the bar 13 by hand, a rod mounted in guides '71 is moved longitudinally, so that the cam member 72 thereon will actuate the latch member 15, so as to throw the lug 18 from the path of the looking bolt 19. This rod 70 may be locked to a lever of the signal post 75 so that the switch cannot be opened, until the padlock 76 is unlocked. However, when the padlock is unlocked the rod 70 may be reciprocated thus actuating the latch member 15. When the bar 13 is moved transversely, it in turn actuates the signal (not shown) by virtue of the rack 75 and pinion 75 with the signal post 75. The signal post 7 5" is provided with a loose sleeve having an arm 7 6 which sleeve is located between the fixed collars 75 Pivoted to the arm 7 6 is a link 76, which terminates in an eye.

-The rod 70 turns upwardly through an opening 70 and to its end a link 7 6 is pivoted. This link 76 terminates in an eye 76, which and the eye of the link 76 receive the padlock '76.

From the foregoing it will be noted there has been devised a novel, simple, eflicient switch mechanism adapted to be automatically operated by a member on the moving car, and one which has been found to be practical.
